Korean bulgogi in lettuce cups comes together faster than calling for delivery. Sweet, savory, high protein — this midweek dinner hits every note.
Mix soy sauce, brown sugar, minced garlic, sesame oil, and black pepper in a bowl to prepare the bulgogi marinade; whisk thoroughly until sugar dissolves.
Add the thinly sliced beef to the marinade, tossing well to coat; let it rest for at least 10 minutes for optimal flavor absorption.
Heat a large skillet over medium-high heat until hot, then add the marinated beef in a single layer; do not overcrowd to ensure browning, cook for 2-3 minutes per side until just cooked through.
Julienne the carrot and thinly slice the scallions while the beef cooks; set aside for garnish and crunch.
Lay out the washed lettuce leaves, fill each with cooked bulgogi, scatter with carrots and scallions, and top with toasted sesame seeds to finish; serve immediately for best texture.
